[00:01.42]He stayed at a hotel where the disease [00:03.46]spread to four more people. [00:05.57]When these people left the hotel [00:07.15]and returned home, [00:08.50]they spread the disease to Canada, [00:10.10]Hong Kong, Vietnam and Singapore. [00:13.46]Over nine months, the number of global cases [00:17.05]surpassed 8,000 and 774 people died. [00:22.03]Although these numbers are much smaller than [00:24.29]the number for other disease such as TB or flu, [00:28.00]which kills millions every year, [00:30.04]the outbreak was still very alarming [00:32.32]for a few key reasons. [00:34.20]No one really knew much about SARS [00:36.80]as it was completely new to physicians. [00:39.25]Doctors weren't sure how to treat it [00:41.11]or prevent it and since most people [00:43.59]had no natural defences against the disease, [00:46.41]it was also harmful to the doctors [00:48.18]and nurses treating the SARS patients. [00:50.80]Hospital staff, especially nurses, [00:52.94]made up 21% of the cases. [00:56.22]Although aspects of modern life, [00:58.21]such as widespread air travel, [01:00.23]allowed the SARS epidemic to quickly expand [01:02.73]across the globe,other aspects, [01:05.02]such as improved communication technology [01:07.62]and improved medical research techniques, [01:10.14]allowed health experts the world [01:11.90]over to share knowledge and work together [01:14.47]to stop the virus in its tracks.
